摘要： A plurality of driving force transmitting members, a piston, a spring and a gas generator are inserted into the pipe from the end of the pipe where the gas generator is mounted. The gas generator is press-fitted in the pipe while the flat faces thereof are deformed by a pair of protrusions of the pipe. Accordingly, the gas generator is temporarily held by the protrusions of the pipe. Then, one end of the pipe is firmly pressed and the gas generator is mounted in the pipe.

摘要： A pipe includes a cutout portion through which levers of a ring gear enter the pipe. An inner peripheral surface of the pipe opposing the cutout portion includes a curved inner peripheral surface in a curved portion of the pipe, a linear inner peripheral surface in a linear portion of the pipe, and a transition portion from the curved inner peripheral surface to the linear inner peripheral surface. The transition portion is located closer to a position where balls start to press the levers of the ring gear, than an intersection where an imaginary straight line α extending from a cutout end portion of the cutout portion intersects an imaginary extension line of the inner peripheral surface of the linear portion of the pipe at a right angle.

摘要： A ring gear 15 of a pretensioner 8 includes a plurality of levers 17 and one arc-shaped stopper 16 to allow force transmission members to smoothly move in a pipe, to facilitate setting of a stopper for stopping rotation of a ring gear, and to reduce the cost with a simple structure. During operation of the pretensioner 8, the levers 17 are sequentially pressed by balls 12a to rotate a pinion 19 and a spool in a seatbelt retracting direction. When the ring gear 15 rotates by a predetermined rotation amount, an outer peripheral edge 16c of the stopper 16 contacts and presses the opposing ball 12a. Since the ball 12a is thereby clamped between the stopper 16 and an inner peripheral surface 10d1 of a pipe I0, the ring gear 15 is stopped.
